V3.24.0 Question about extra sensors dew point on select-a-chart

[broadstairs]

Though I'd ask in case it is a yygt (yes you get that ). I was checking my dashboard select-a-chart and noticed that when I have to restart CMX the dew point only for my extra temp/hum sensors both drop to zero and then recover just fine. Now I know that CMX has to calculate this value but in case anyone tries to look for minimum values in records this will show zero which is not valid. It's only dew point does this, the temp/hum values do not drop at all.

Can we first establish terminology

When you say "extra sensors", do you mean additional sensors attached to your main station, or an extra sensor station in addition to your main station?

Which one helps me look in the right place in the code.

Think there was another post about extra sensors dropping to 0 on a restart. I have seen it happen in the last few weeks since setting up / playing around with my extra sensors as I have noticed a line of all 0 (zeros) go into the ExtraLog text file after a restart.

Just stopped and started Cumulus at 10:32 and when restarted the log file was fine, however stopped again at about 10:37, and then restarted about 10:40 and I got the following:

For me, it's extra sensor station.

Just tried again, this time shutting down at 10:47 and restarting at 10:51 (so not on an exact 10 minute logging interval), and got a line of zeros again:

Yep. I'm aware of the extra sensor station issue, I wanted to establish if this is the same issue of different.

It sounds like it is different because the T & H are being recorded.
